FULLNAT: A new packet forwarding model as DR/NAT/TUNNEL

The main principle: introduce local ip address (IDC internal ip address, lip), IPVS translate cip-vip to lip-rip, lip and rip both are IDC internal ip address, so LVS-RS can be inter-vlan communication, and RS only need access to internal network.

The first FULLNAT and SYNPROXY modules were added to IPVS in Linux kernel 2.6.9 by WenLi,YanTian,JianChen,YangYi,YaoguangSun, FangHan,Yingliu and JiamingWu. Now, the second FULLNAT and SYNPROXY modules were added in Linux kernel 2.6.32 by JianChen,JiamingWu and WensongZhang;

The FULLNAT and SYNPROXY support was add to keepalived/ipvsadm by JiajunChen,ZiangChen and ShunminZhu.
